Mantra is a form of elemental protection found on all of the Monk's defensive equipment that works similarly to armor but protects Monks against Fire Damage, Ice Damage, Energy Damage and Earth Damage exclusively by a flat amount.

It does not reduce damage over time, however, meaning you can step on a Fire Field and take no damage from it but you'll take damage from the Burning condition caused by it.

The total value of mantra is doubled when a monk is in Serene form.
